Find the volume of 56.0 grams of O2
N76 [4]

Answer:

39.2 L at STP

Explanation:

Convert the grams to moles first by dividing 56.0 by the molar mass of O2 (32.0) then convert to volume by multiplying by 22.4.

= 39.2 L

is carried out adiabatically in a constant-volume batch reactor. The rate law is Plot and analyze the conversion, temperature, a
Sphinxa [80]

Answer:

See explaination

Explanation:

The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.

Please kindly check attachment for the step by step solution of the given problem.

How you could use the scientific method to learn whether water really does take longer to boil if you are watching it.​
Alenkasestr [34]

Answer:

Please find the detailed explanation below

Explanation:

A scientific method is a sequence of steps that is used to solve a problem. Every scientific method begins with a problem that needs to be solved.

Hence, in order to determine whether water really does take longer to boil if you are watching it, we employ the steps involved in a scientific method.

1) Ask a question/Make observation: This must initiate the process. The observation/question made here is that DOES WATER TAKE LONGER TIME TO BOIL WHEN WATCHED?

2. Formulating hypothesis; an hypothesis is a testable prediction of a possible solution to the stated problem. In this case, an hypothesis could read: IF water is watched while boiling, THEN it will take a longer time to boil. A hypothesis must be tested for it to be proved or disproved.

3. Test hypothesis: The formulated hypothesis is tested via conducting an experiment. The set up of the experiment can involve one group where water is boiled while watching it and another where water is boiled without watching. The former group is called Experimental group, while the latter group is called Control group. The time it takes for each group of water to boil will be recorded.

The independent variable (manipulated variable) will be the WATCHING, while the dependent variable (tested/responding variable) will be the TIME IT TAKES FOR WATER TO BOIL

4. Analyse the data; the data refers to the recorded time for each group of water. This will be analysed and compared.

5. Make conclusion; the conclusion depends on the result, which is the recorded time for each group of boiled water. Based on the result, the hypothesis can either be rejected or accepted. For example, if the control group boils faster than the experimental group, our hypothesis will be accepted but if otherwise, the hypothesis will be rejected.

Therefore, via the scientific method, it can be determined if it really takes longer time for water to boil while watched.
